Being an aerospace engineer and a FCEV driver ( been hauling around 10 ksi tanks for over 7 years now without incident), I don't have a reflexive reaction to the tanks themselves. I trust Tesla quality a lot less though, and I don't see much of a safety barrier between the tank and the driver.
Ah, the auto influencers have explained that this carbon fiber-wrapped ball, which sits right behind the driver's head, holds about 100kg of nitrogen pressurized to about 10,000 psi. Let me just go review the tolerances people found in their Cyber Trucks
In 'Rendezvous with Rama', Arthur C. Clarke laid out some fictional history, and I remember thinking it was odd he felt like including a mention of African nations have a run of dominance in the World Cup in the 2030s. But it's 2026, and it looks like he may have been on to something. Well done.
really cool going from the 2010 World Cup, where Ghana’s little run seemed like a magical anomaly, to a bunch of African teams contending across the bracket and participating in the global pastime of causing fear and misery in England.

he's counting on people not knowing what a doctor looks like because they don't have healthcare
Reporter: Did you post that picture of yourself depicted as Jesus Christ? Trump: It wasn't a depiction. I did post it and I thought it was me as a doctor. And had to do with red cross as a red cross worker, which we support and only the fake news could come up with that one.

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

There's been a lot of debate within the Democratic establishment about what rhetoric to use via ICE. Well, an incumbent doesn't lose by 48 percentage points very often—and her vote on collaborating with ICE was the defining issue here.
JUST IN: North Carolina's Dem lawmaker Carla Cunningham gave the GOP the decisive vote to pass a law forcing police to comply with ICE. She said "all cultures are not equal." She just lost reelection BIG in the Dem primary to a progressive pastor & activist, Rodney Sadler. 70% to 22%! Context:

Yesterday morning kids were sent running from their bus stop in panic because ICE showed up. This guy at today’s ICE Out of Lindenwold protest is a must watch 😭. @maddow.bsky.social

I cannot stress enough that you should not do this.
Yeah sure, most oil co's wouldn't want Venezuela's oil assets, but there is one that very clearly does want a return on its investment, owned by a GOP megadonor, and it's been in the news. But turning off the comments makes it hard for people to tell you about it share.google/LId62Y475qn1...
The amount of “this is clearly about oil” posting across all platforms as story after story comes out where the oil industry is saying that the oil isn’t worth extracting is making me feel a little insane

If you’re wondering why your friends in academia are a little on edge right now, it’s because an eighteen-year-old who hasn’t done the reading, doesn’t look at the assignment, and has does no critical thinking skills more complex than “because I think it’s in the Bible” can literally end your career
The University of Oklahoma has removed an instructor who was accused by a student of religious discrimination over a failing grade on a psychology paper in which she cited the Bible and argued that promoting a “belief in multiple genders” was “demonic.” https://cnn.it/4b6g3rd

I remember hearing about this when it happened. The fake police parked their fake police car in the street during an abduction raid. This hero towed it, and the video of them helplessly chasing him is pretty great. So glad he was found not guilty. Justice was done. abc7.com/post/man-acc...
